Definitions
- This invention relates to home exercise equipment.
- the invention relates to a chin-bar that may be installed within a doorway of a home and that is adjustable to accommodate users of different heights.
- Door mounted exercise bar devices are known in the art. Exercise bar devices are taught in U.S. Pat. No. 3,915,452 to Winblad for a “Portable Chinning Bar Assembly”, U.S. Pat. No. 4,529,191 to Miller, et al. for a “Doorway Mounted Horizontal Bar”, U.S. Pat. No. 5,417,628 to Vanderbleek for an “Exercise Device for Chin-Ups” and U.S. Pat. No. 5,180,350 to Thomas for an “Exercise Bar Apparatus”.
- the related art devices teach various methods and devices for mounting an exercise bar within a doorway.
- the apparatus of the invention is a doorway mounted chin-up bar device having a rod that secures to an inside of a doorway.
- the rod is comprised of an interior tube and an exterior rotating sleeve, wherein the interior tube is received in telescoping engagement within the rotating sleeve.
- a mount is positioned on each end of the rod for securing the rod within the doorway.
- a pair of approximately U-shaped extension bars are pivotally affixed perpendicularly to the rod.
- the extension bars extend outward from the rod and extend upward.
- the extension bars have a first end that extends out of a plane defined by the doorway in a first direction and a second end that extends out of the plane of the doorway in a second direction.
- a first hand-grip bar is affixed to the first end of the extension bars and a second hand-grip bar is affixed to a second end of the extension bars.
- the extension bars pivot about the rod until the second hand-grip bar engages a wall surface above the doorway. The user may proceed to engage in chin-ups while being supported by the first hand-grip bar.
- the user may grasp the second hand-grip bar and pull down.
- the extension bars will pivot about the rod until the first hand-grip bar engages the wall surface above the doorway.
- the second hand-grip bar may then support the user while the user engages in chin-ups.
- the first hand-grip bar may be located further away from the rod than the second hand-grip bar. Since the first hand-grip bar and second hand-grip bar may be at different distances away from the rod, the height from the floor of a hand-grip bar may vary according to whether the user is being supported by the first hand-grip bar or the second hand-grip bar.
- FIG. 1 is a perspective view of the chin-up device of the invention.
- FIG. 2 is a perspective view of the chin-up device of FIG. 1 shown installed within a doorway.
- FIG. 3 is an elevational cross-sectional view of the device in FIG. 1, shown wherein the first hand-grip bar is positioned for use.
- FIG. 4 is a cross-sectional elevational view of the device of FIG. 1 wherein the second hand-grip bar is positioned for use.
- FIG. 5 is a plan view of a second embodiment of the invention wherein the first hand-grip is irregularly shaped so that a portion of the hand-grip is parallel to the extension bars.
- Chin-up bar apparatus 10 is designed to be installed between the door-jambs 12 and 14 of doorway 16 having a wall surface 19 thereabove (FIG. 2 ).
- Chin-up bar apparatus 10 has a rod 17 having a fixed end 18 and a telescoping end 20 .
- a mount 22 is positioned on fixed end 18 of rod 17 and a mount 24 is positioned on telescoping end 20 of rod 17 .
- Mounts 22 and 24 engage door-jambs 12 and 14 and may be secured to door-jambs 12 and 14 by screws. Additionally, supports (not shown) may be secured to door-jambs 12 and 14 that are designed to receive mounts 22 and 24 .
- rod 17 is made up of a rotating sleeve 26 that telescopically receives interior tube 28 . Rod 17 may, therefore, be adjusted in length to accommodate various widths of doorway 16 .
- extension bars 30 a and 30 b are clamped to exterior rotating sleeve 26 with clamps 31 . Therefore, extension bars 30 a , 30 b may pivot about rod 17 .
- Extension bars 30 a , 30 b each have a straight portion 32 and two curved ends 34 and 40 . Straight portion 32 is secured by clamps 31 to rotating sleeve 26 . In the preferred embodiment, clamps 31 are located closer to curved portions 40 than to curved portions 34 .
- short extension bar portions 36 do not extend as far from rod 17 as long extension bar portions 37 .
- Padded sleeves 42 may be provided on straight portion 32 and curved portions 34 , 40 to protect the user and for aesthetic purposes.
- a first hand-grip bar 44 is affixed transversely between the curved ends 34 of extension bars 30 a , 30 b .
- First hand-grip bar 44 has a first end 44 a and a second end 44 b , which are at 90° relative to bar 44 and insert into curved ends 34 .
- a padded hand-grip 46 is provided on first hand-grip bar 44 .
- a second hand-grip bar 48 having a first end 48 a and a second end 48 b is affixed to curved ends 40 extension bars 30 a , 30 b .
- a padded hand-grip 50 is provided on second hand-grip bar 48 .
- Hand-grip bars 44 , 48 are parallel to each other and to bar 17 .
- the chin-up bar of the invention is installed within a doorway 16 . Screws may be used to secure mounts 22 and 24 to door-jambs 12 and 14 .
- the chin-up bar apparatus 10 is located so that hand-grip bar 48 contacts the wall surface 19 above doorway 16 when tilted up as shown in FIG. 4 .
- the user approaches the chin-up bar apparatus 10 and selects either the first hand-grip bar 44 or second hand-grip bar 48 to grasp and pull downward. If the user selects first hand-grip bar 44 , the extension bars 30 a and 30 b , along with hand-grip bars 44 and 48 will pivot about rod 17 along with sleeve 26 .
- Second hand-grip bar 48 will move up towards the ceiling and into engagement with a wall surface 19 above a doorway 16 .
- the chin-up bar apparatus 10 is in position to support a user's weight from the first hand-grip bar 44 (FIG. 4 ).
- the user may elect to grasp the second hand-grip bar 48 , which will pivot the extension bars 30 a and 30 b , along with hand-grip bars 44 and 48 about rod 17 until the first hand-grip bar 44 engages wall surface 19 above the doorway 16 .
- the second hand-grip bar 48 is prepared to support the weight of a user. (FIG. 3 ).
- the first hand-grip bar 44 is a first distance from a floor surface when the chin-up bar apparatus 10 is in a first position (FIG. 4) and the second hand-grip bar 48 is a second and different distance from the floor when the chin-up bar apparatus 10 is in a second position (FIG. 3 ). Therefore, the chin-up bar apparatus 10 of the invention can easily accommodate users of different heights by providing first and second hand-grip bars 44 and 48 , which are two different heights from the floor when in position for use.
- first hand-grip bar 44 and/or second hand-grip bar 48 may be of an irregular shape.
- An example includes a configuration wherein a portion of the hand-grip bar 44 and/or 48 are parallel to the extension bars 30 a and 30 b .
- hand-grip bar 48 has been replaced with irregular hand-grip bar 52 in FIG. 5 .
- Bar 52 has offset portion 54 , which is in the center of hand-grip bar 52 and offset from outside portions 56 .
- Portions 56 are parallel to the plane of extension bars 30 a and 30 b in the preferred embodiment.
- An irregularly shaped hand-grip bar allows the user to grip the hand-grip bar in a different manner for the purpose of exercising different muscles. Additionally, other hand-grip bars of other irregular shapes besides that shown in FIG. 5 may be provided.
- a user may grasp offset portion 54 of irregularly-shaped hand-grip bar 52 (FIG. 5) to engage in a variation of the traditional chin-up exercise.
- irregular shaped hand-grip bar 52 is shown on only one side of the chin-up bar apparatus 10 , an irregularly shaped hand-grip bar 52 may be utilized on one or both sides of chin-up bar apparatus 10 .
- the chin-up bar apparatus of the invention has several advantages.
- the chin-up bar enables a quick and easy change between two heights of the hand-grip bar to enable users of different heights to use the apparatus. Additionally, the chin-up bar apparatus may be easily installed within doorways of different widths. Further advantages are apparent from the preceding specification.
- each extension bar may be formed from several pieces rather than an single piece.
- the first hand-grip bar may be integrally formed with the extension bar and the second hand-grip bar may be integrally formed with the extension bar.
- additional irregularly-shaped hand-grip bars may be utilized to further vary the exercises available to a user.
- the apparatus of the invention may be used for exercises other than chin-up devices and may have special adaptive equipment provided on the hand-grip bar to facilitate such exercises.
